Building Turing Geovisualization Engine with R

Intro

• Institutions: Leeds Institute for Data Analytics & Turing Institute

• Project: Dr. Nik Lomax and Dr. Roger Beecham

• Research Theme: Urban Analytics, Sir Alan Wilson and Prof Mark Birkin.

• May 2019 - Oct 2020

• More geo-visualization than research engineering or engineering research.

Talk Overview

< image >

• Data visualization which means graphics which means using CPU and/or GPU
  • Ubiquitous (Lyytinen and Yoo 2002)
  • Interactive (Benyon 2014)
    • design, technology, people, activities
• R doing what it does (best?): data analysis
• Turing Geo-visualization Engine (TGVE)

The story of a Graphics Processing Unit (GPU)

Why R

• One of two choices (Python which I would have prefered) both being Open Source
  • Being Open Source not so fancy any more?
• Colleagues who use R around University of Leeds.
• Focus on Grammar of Graphics (Wilkinson 2005) and other academic excellence such as ggplot2 (Wickham 2016)
• That also means a great set of tools
• You might have better reasons.
